ABSTRACT

The cell surface of a non-fruiting myxobacterium,Cytophaga johnsonii, was investigated by electron optical techniques. Negative staining revealed an irregularly undulating surface topography and the presence of strands of material arising from the cells. Replicas of freeze-dried cells and thin sections confirmed the uneven nature of the surface and showed that, in contrast to eubacteria, the cell was surrounded by an envelope of amorphous, electron-translucent material contained within a crenated, outer, “unit” membrane. This material could be extruded as long strands. It is considered that this envelope of material represents the slime layer of the organism.The appearance of the slime layer at various stages in the growth of the organism was followed by negative staining and the image of the organism presented by negative staining was compared to that given byMyxococcus xanthus andFlavobacterium aquatile.
